For the back method of the safety monitoring video, including at least a kind of following mode:Institute is directly played in order State each frame monitored picture in image library;And screen is shown in by the moment is absorbed corresponding to each frame monitored picture, it is such as a certain Frame picture corresponds to continuous multiple intake moment, then only shows the head and the tail moment at continuous multiple moment.
The back method of above-mentioned safety monitoring video, its advantage are:For continuous static picture in monitored picture Face, a frame is directly reduced to, therefore, plays back and dynamic event in monitoring range is only presented in video, and a series of this dynamic Event is just the key message obtained needed for monitoring playback operation, therefore, in process of playback of video, is believed for useless video The viewing time of breath is reduced to minimum (time of a frame picture is extremely short), and the stand-by period that makes to solve a case almost realizes nil waste, Efficiency of solving a case greatly improved.
Embodiment
The present invention is further described below:
For the storage method of the safety monitoring video, comprise the following steps:
First, using the intake moment of each frame monitored picture as element, an one-dimensional timetable is worked out;First frame monitored picture is taken the photograph The original position for being added to the timetable constantly is taken, hereafter, the intake moment of each frame is added to the end of the timetable.
2nd, the image library of a storage monitored picture is established, the intake moment of the first frame monitored picture is added to described After the original position of timetable, the view data of the first frame monitored picture is stored in described image storehouse;And establish the monitoring of the first frame Mapping between the intake moment of picture and view data.
3rd, for each frame monitored picture, the moment is absorbed added to behind the end of the timetable;By its picture number According to compared with the view data corresponding to former frame monitored picture, when both differences are in prescribed limit, present frame is abandoned View data, and the intake moment of present frame is mapped to the view data corresponding to former frame monitored picture;If both differences Beyond prescribed limit, then the view data of present frame is stored in described image storehouse, and establish intake moment of present frame picture with Mapping between the view data of present frame.
When storing the monitored picture, a M × N corresponding with the resolution ratio of monitored picture square is initially set up Battle array;Then each element using the color value of each pixel of monitored picture as the matrix.
, can be as follows when comparing the view data of two frame monitored pictures:1st, it is two frame monitored picture institutes are right The image array answered directly makees difference, obtains a difference matrix;2nd, the quadratic sum of each element in the difference matrix is calculated, it is described When quadratic sum is less than setting, it is determined as the view data of the two frames monitored picture without departing from prescribed limit.Which belongs to The conventional method of image comparison, is characterized in, contrast is accurate, as long as two images are different, that is, is considered different images.But It is in the case of more, there is the problem of monitored picture shake, in the case, not occur security protection event actually, but Need to store multiframe monitored picture, it is clear that there is also the problem of waste of storage space.
Therefore, two frame monitored pictures can be compared using following method:1st, it is right for each frame monitored picture institute The image array answered, calculate each color value and around it each color value poor side's sum, as corresponding to each element Partial structurtes value;2nd, the structured value summation of all elements in each frame monitored picture is calculated, as general construction value;3rd, described in calculating The difference of the general construction value of two frame monitored pictures;If the difference of the general construction value is less than setting, it is determined as the two frames monitoring The view data of picture is without departing from prescribed limit.For the two frame monitored pictures shot under dither state, image corresponding to them There are a large amount of identical elements in matrix, the position where only corresponding to identical element is different, but these elements and surrounding Data relation is constant between element, therefore, is contrasted again after this kind of data relation is taken statistics, you can Solves the repetition storage problem under float state.
According to the deposit method of above-mentioned safety monitoring video, in monitoring range, actionless picture in continuous time Face, a frame is only stored in storage device;In fact, for substantial amounts of monitoring range, due to not having in its most time Personnel come in and go out, and therefore, picture is substantially fixed, and for the picture that this kind of long-time is static, such as each frame is all independently stored in Storage device, then amount of storage is extremely huge, will consume substantial amounts of space, serious waste carrying cost;And according to the method described above, then It on the basis of monitoring information is not lost, will greatly reduce the parking space of monitoring information.
For the back method of the safety monitoring video, including at least a kind of following mode:Institute is directly played in order Each frame monitored picture in image library is stated, and screen is shown in by the moment is absorbed corresponding to each frame monitored picture, it is such as a certain Frame picture corresponds to continuous multiple intake moment, then only shows the head and the tail moment at continuous multiple moment.
